Description

永磁式排水泵
技术领域
本实用新型涉及一种水泵。具体说,是家用洗衣机上的永磁式排水泵。
背景技术
在洗衣机制造行业都知道,洗衣机上都设置有排水泵。传统的排水泵包括泵壳和电机,泵壳上有轴孔、进水口和出水口,电机的输出轴通过轴孔伸入泵壳内,泵壳内有叶轮,所述叶轮与电机的输出轴相连。洗衣机运行过程中完成一个程序需要排水时,由控制程序来启动电机旋转的同时,泵壳上的进、出水口被打开,洗衣机内的水流经进水口后进入泵壳内,通过叶轮旋转从出水口排出在外。由于这种排水泵的进水口处在泵壳上,洗衣机排水时,洗衣机内的水直接进入泵壳内,被洗衣物中掉落的纤维和硬币等杂物进入泵壳后,不仅会堵塞洗衣机排水口,还会损坏叶轮,因此,采用传统排水泵的洗衣机,故障率较高。
实用新型内容
本实用新型要解决的问题是提供一种永磁式排水泵。采用这种永磁式排水泵,可大大降低洗衣机故障率。
为解决上述问题,采取以下技术方案:
本实用新型的永磁式排水泵包括泵壳和电机,泵壳上有轴孔、进水口和出水口,电机的输出轴通过轴孔伸入泵壳内,泵壳内有叶轮,所述叶轮与电机的输出轴相连。其结构特点是与电机的输出轴垂直的泵壳一面上通孔,通孔外侧有外伸筒,外伸筒的外端有旋钮,旋钮内侧的外伸筒内有过滤筒,过滤筒一端与旋钮相连,另一端与所述通孔的周边相抵。外伸筒的侧壁上有进水口。
其中,所述过滤筒含有内圆盘和外圆盘,内、外圆盘间有网筒,内圆盘中心有通孔,所述网筒两端分别与内圆盘和外圆盘形成为一体。泵壳上的出水口和外伸筒上的进水口分别处于相对的两侧。
外伸筒的外端有内螺纹,旋钮上有外螺纹,旋钮借助其上的外螺纹和外伸筒外端的内螺纹旋入外伸筒的外端内。
采取上述方案,具有以下优点:
由上述方案可以看出,由于与电机的输出轴垂直的泵壳一面上加工通孔,通孔外侧有外伸筒,外伸筒的外端有旋钮,旋钮内侧的外伸筒内有过滤筒,过滤筒一端与旋钮相连,另一端与所述通孔的周边相抵。外伸筒的侧壁上有进水口。洗衣机排水时,洗衣机内的水进入外伸筒侧壁上的进水口,通过网筒的过滤后,再通过网筒里端的通孔进入泵壳内,被洗衣物中掉落的纤维和硬币等杂物被拦截在网筒之外,避免了洗衣物中掉落的纤维和硬币等杂物堵塞洗衣机排水口、损坏叶轮的情况发生。从而大大降低了洗衣机的故障率。
附图说明
图1是本实用新型的永磁式排水泵结构示意图;
图2是图1中的过滤筒立体示意图。
具体实施方式
如图1所示,本实用新型的永磁式排水泵包括泵壳2和电机1,所述泵壳2为近似圆盘形,其外侧壁上加工有出水口3,其一面的中心加工有轴孔,其另一面加工有通孔,电机1的输出轴12通过轴孔伸入泵壳2内。泵壳2内设置有叶轮4,所述叶轮4的中心加工有轴孔,叶轮4借助其中心的轴孔固定在电机1的输出轴12上。带有通孔的泵壳2一面上设置有外伸筒5,该外伸筒的里端与所述通孔四周的泵壳2形成为一体。外伸筒5的外端设置有旋钮7,旋钮7上加工有外螺纹,外伸筒5的外端加工有内螺纹,旋钮7借助其上的外螺纹和外伸筒5外端的内螺纹旋入外伸筒5的外端内。外伸筒5的侧壁上加工有进水口11。
如图2所示,旋钮7内侧的外伸筒5内设置有过滤筒,过滤筒一端与旋钮7相连,另一端与所述通孔的周边相抵。所述过滤筒含有内圆盘10和外圆盘6,内圆盘10与外圆盘6间设置有网筒8,内圆盘10中心加工有通孔9,所述网筒8两端分别与内圆盘10和外圆盘6形成为一体。
泵壳2上的出水口3和外伸筒5上的进水口11分别处于相对的两侧上。外伸筒5的外端加工有内螺纹,旋钮7上加工有外螺纹,旋钮7借助其上的外螺纹和外伸筒5外端的内螺纹旋入外伸筒5的外端内。
洗衣机排水时,洗衣机内的水经过外伸筒5侧壁上的进水口11、再穿过网筒8侧壁和内圆盘10上的通孔9后,进入泵壳2内,在叶轮4的作用下,出水口3排出。
